TIMING CHART

Re-ignited PTFI on flame fail after Terminal 5 energized.

Recycle on loss of air flow after flame proven.

MP101

Same as MP100 but will tolerate flame signal during “Off” cycle.

APPLICATION AND FUNCTION - MP101

The MP101 operates in the same manner as the MP100 with the following exception. The MP101

programmer module will not lock out if flame signal is detected during the off cycle (no power on

terminal 7). If flame signal is present when power is applied to terminal 7, the control will not lock

out until the air flow switch is proven closed (power on terminal 6).

Consult the factory before installing the programmer.

APPLICATION AND FUNCTION MP230

The MP230 Programmer Module directly replaces the Fireye M2 Series “recycle” controls and M3

Series “non-recycle” controls. It provides prepurge, ignition and flame safeguard for heating and

process light oil or gas fired burners. The “recycle” or “non-recycle” operation is determined by the

position of dipswitch #8 on the Programmer Module. Purge timing, as well as trial for ignition timing

is also set by the dipswitch settings. See PROGRAMMER DIP-SWITCH SETTINGS on page 11.

Amplifier and Scanner Selection

The Amplifier Module should be selected base on the type of flame scanner (UV scanner or flame

rod), and the required Flame Failure Response Time (F.F.R.T.). See ORDERING INFORMATION

on page 4 for the appropriate part numbers.

Pilot Ignited Burners - “Recycle” Operation

With dipswitch #8 in the “recycle” position, the typical wiring arrangement illustrated on pages 26

(MC120, MC230) or 28 (MC120P) for pilot ignited burners provides the following function:

1. With power applied, and the limit-operating control circuit closed (Operating Control LED lit),

the burner motor circuit is energized. The air flow circuit closes (Air Flow LED lit).

2. Following the prepurge period (as determined by dipswitches #1 through #5), KL-1 closes, ener-

gizing Terminal 3 which powers the pilot gas valve and Terminal 4 which powers the spark igni-

tion. A five or ten sec. (as determined by dipswitches #6 or #7) trial for ignition is initiated

(PTFI LED lit).

3. When pilot flame is detected (Flame LED lit), KF-1 closes, energizing Terminal 5 which pow-

ers the main fuel valve, KF-2 opens de-energizing Terminal 4 which shuts off the spark ignition.
